The option to control copy parametrization (Change value of variable) is available for linear arrays.

To create a parametric array, you should type a variable name into the Change value of variable input box and select a mode in the adjacent drop-down list.

The variable takes the value either in accordance with the copy number (By number of copy mode), or in accordance with the distance from the beginning of the trajectory (By length mode).

Example

It is necessary to create an array of rectangles, where the height of the rectangle will be increased by 15 mm for each subsequent copy.

Construct a rectangle. The height of the rectangle will be determined by the variable H. In the variables editor for the variable H, write the expression: H=50+N*15, where N is a changeable variable of the array.

Create a linear array in which, in the option Change value of variable, you should specify the variable N and choose the option of changing By number of copy.

As a result, the next array will be obtained.
